Cobblestone Monster Egg

Cobblestone Monster Eggs are blocks that look exactly like stone, but when broken spawn silverfish. They are only found in strongholds, and can be used to troll and unexpecting player. If Cobblestone Monster Eggs are destroyed by a Creeper or TNT, the silverfish will be killed and will not spawn. Stone Monster Eggs, Cobblestone Monster Eggs, and Stone Brick Monster Eggs all do the same things.
